I just bought a Laney AOR Pro tube 50w. I plan on buying a Bugera 120w cabinet.

Bugera Information

With 140 Watts of explosive power handling, this vintage cabinet is the perfect complement to Bugera amps
Original 2 x 12'' BUGERA Vintage Guitar Series speakers
Versatile 4/16-Ohm mono or 2 x 70-Watt, 8-Ohm stereo configuration
Stylish and comfortable carrying handle for easy single-handed transportation
Extremely low-resonance and low-vibration cabinet
Reinforced corners and protective vinyl covering
High-quality components and exceptionally rugged construction ensure long life

I'm not sure what the ohm's are on the laney.
I just want to know If I can just plug em' in and play. Can I?

looks like you can choose impedance output on the laney, looks like you can choose 4, 8 or 16.

you're fine

you'll need to turn the switch on the back to 16 ohm on the laney and make sure the bugera is operating at 16 ohms
punk isn't dead, it's always smelled that way.
